近几年来,中速船用柴油机在喷油开始时气缸压力已有显著的增加,这个增加要求对高温高压下的燃烧过程进行基本研究。从这点出发,作者设计了一台高压容器用于喷射燃料雾化的试验和一台定容燃烧室用于燃烧过程的试验。这两个燃烧室能够用比以前使用的还高的工质压力进行柴油机的燃烧研究和摸拟中速船用柴油机的燃烧过程。 In recent years, medium-speed marine diesel engine at the beginning of injection cylinder pressure has increased significantly, this increase requires a basic study of the combustion process under high temperature and pressure. From this point of view, the author designed a high pressure vessel for jet fuel atomization tests and a constant volume combustion chamber for combustion tests. Both of these combustors are capable of carrying out diesel combustion studies and simulating the combustion of medium-speed marine diesel engines at higher working fluid pressures than previously used.
